In the event .of an accident inthe field, by which ablade is broken or injured, the exchange is made in a few moments and the work proceeds at once.

. Furthermore, the sickle-blades may all be readily taken 011t,when desired, for sharpening or the machine.

SPECIFICATION forming part; of Letters Patent No. 288,342, dated November 18. 1883.

Application filed July 10, 1883. (No model) low ball, E, to which the pitman F is connected.

A recess, 0, is provided in the underside of the frame 0, (see-Fig. 6,) the broader part, c, of said recess accommodating the butt ends of the cutting-blades. The bar or stripBiits into the recess 0, and is seouredto the frame 0 by the bolts and nuts (I d and the holes d d through the bar Band the frame 0. The headlsof the bolts (2 are preferably sunk in the'bar B. This lowerbar, B, has formed on its upper side the; fixed diamond-shaped blocks b b, (see Fig. 5,) at proper intervals to receive between them the blades G G. On each side of the base of .each sickle-blade G is provided a recess 9 g, adaptedto fit snugly against the side of the block b Z). (See Fig. 5.) The height of the blocks 1) is equal to the thickness of the blades. G. The strip or bar A, of about equal width and thickness with the .bar 13, extends from the frame 0, parallel with the bar B, and is designed to securely hold the blades Gin op erative position. the bar A, the blocks b and lower bar, B, are provided for the screws I I, by which these parts are firmly held together. (See Fig. 3.) The notches g g in the blades Gand theblocks b bare made of uniform dimensions, so that any of the blades will fit between any two of the blocks. This arrangement of the strips and frame give strength and firmness to the bar, and hold the cutting-blades firmly when the machine is in operation.

The pitman F, Fig. 1, is furnished with two arms, one of which, 1, is fixed upon the pitman F, and the other, I, is pivoted to the said rod or pitman. These arms Z l are broadened at their working ends and formedinto sockets, which, as the arms are brought toward each other, close upon the ball E, in which position is preferably made hollow, to secure greater lightness, anda supply of oil in its concavity will lubricate its exterior through the small opening 6.

To takeout all the teeth from the cutter-bar,

Threaded holes a a, through they are held by the set-screw m. The ball E 2 zss,342

be lifted from its bed, when by moving it to one side until the notch g encounters the screw I the other corner of the base will pass the other screw, and the tooth is readily drawn out at the front of the cutter-bar. By the same movement reversed another tooth is inserted, and the strip a, which should be of steel, when released, closes down upon the tooth, and the screws are again put in place. Both of the bars'A and B are preferably made of steel; but other material may be used, if desired, and I do not confine myself to the use of any particular material in constructing any of the parts of my invention.

,1 am aware of patents granted to Arnold June 29, 1875, No. 164,958; to Hovery April 29, 1856, No. 14,768; to Cree's July 19, 1881, N 0'. 244,435, and to Tilley& Sanford January 2, 1883, N 0. 269,899, for cutting apparatus, and do not claim them as my invention.

Having now described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

In a cutter-bar, the combination of the strip or bar A, having screw-holes a a, the strip or bar B, having the fixedelevations or blocks 7) b and threaded holes a a, the end frame, 0, having recesses c c and holes d d, the bolts and nuts (1 d, the screws I I, the sickle-blades G G, having the angular recesses 99, and suitable means for connecting the cutter-bar to the pitman 13, all constructed substantially in the manner and for the purposes herein set forth.

In testimony whereof I affix mysignature in presence of two witnesses.

MARTIN W. KIEFER.
